Abstract
Abstract The invention provides a system and a method for lifting and transporting vehicles, such as a snowmobile or other recreational vehicle. The system includes a frame member having a first rail member and attached to a vehicle, a second rail member moveable along the first rail member into a deployment position wherein it extends rearwardly of the frame, a moveable support member which can extend supportively between the second rail member and the ground, and a platform member slidable along the first and second rail members. The method of the invention may employ a system of the invention and involves moving a second rail member into a deployment position extending rearwardly of a frame, moving a support member into position to support the second rail member, sliding a platform rearwardly along first and second rail members to position the platform generally rearwardly of the transport vehicle, and lowering the rearward end of the second rail member to position its rearward end adjacent the ground for loading the vehicle onto the platform.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
158 words
A system for loading and unloading a recreational vehicle onto a transport vehicle comprising: a) a frame member affixed to the transport vehicle, the frame member including first rail means; b) second rail means cooperating with the first rail means, the second rail means being moveable along the first rail means from a storage position to a deployment position wherein the second rail means extend rearwardly of the frame; c) support means carried adjacent a rearward end of the second rail means, the support means being moveable relative to said second rail means between a storage position and a support position wherein the support means extends supportively between the second rail means and the ground; and d) platform means slidable along the first and second rail means between a first position wherein the platform means is disposed above a bed of the transport vehicle and a second position wherein the platform means is disposed rearwardly of said bed.
Claim 2
Independent Claim
158 words
A system for loading and unloading a recreational vehicle onto a transport vehicle comprising: a) a frame member affixed to the transport vehicle, the frame member including first rail means; b) second rail means cooperating with the first rail means, the second rail means being moveable along the first rail means from a storage position to a deployment position wherein the second rail means extend rearwardly of the frame; c) support means carried adjacent a rearward end of the second rail means, the support means being moveable relative to said second rail means between a storage position and a support position wherein the support means extends supportively between the second rail means and the ground; and d) platform means slidable along the first and second rail means between a first position wherein the platform means is disposed above a bed of the transport vehicle and a second position wherein the platform means is disposed rearwardly of said bed.
Claim 3
Dependent Claim
60 words
The system of claim 1 wherein the second rail means is pivotally connected to the first rail means, the second rail means being pivotable from a substantially horizontal orientation for sliding the platform means and an inclined orientation wherein the second rail means extends from a forward end adjacent the first rail means and a rearward end adjacent the ground.
Claim 4
Dependent Claim
29 words
The system of claim 2 wherein said support means further comprises mechanical lifting means for moving the second rail means between its substantially horizontal orientation and its inclined orientation.
Claim 5
Independent Claim
172 words
A method of unloading a recreational vehicle from a transport vehicle comprising the steps of: a) providing a frame member affixed to the transport vehicle and including first rail means, second rail means movable from a storage position and a deployment position, support means movable from a storage position and a support position, and platform means slidable along said first and second rail means; b) moving the second rail means to its deployment position wherein the second rail means extends rearwardly of the frame member; c) moving the support means into its support position so that the support means extends from the second rail means to the ground to support the second rail means; d) sliding the platform rearwardly along said first and second rail means to a position wherein the platform is disposed generally rearwardly of the transport vehicle; e) lowering a rearward end of the second rail means so that the second rail means extends between a forward end adjacent the first rail means and rearward end adjacent the ground.
Claim 6
Independent Claim
172 words
A method of unloading a recreational vehicle from a transport vehicle comprising the steps of: a) providing a frame member affixed to the transport vehicle and including first rail means, second rail means movable from a storage position and a deployment position, support means movable from a storage position and a support position, and platform means slidable along said first and second rail means; b) moving the second rail means to its deployment position wherein the second rail means extends rearwardly of the frame member; c) moving the support means into its support position so that the support means extends from the second rail means to the ground to support the second rail means; d) sliding the platform rearwardly along said first and second rail means to a position wherein the platform is disposed generally rearwardly of the transport vehicle; e) lowering a rearward end of the second rail means so that the second rail means extends between a forward end adjacent the first rail means and rearward end adjacent the ground.
Claim 7
Dependent Claim
39 words
The method of claim 4 wherein the second rail means is pivotally connected to the first rail means, wherein the second rail means is pivoted about said pivotal connection to lower the rearward end of the second rail means.
Claim 8
Dependent Claim
13 words
The system of claim 1 wherein the support means has an adjustable length.
Claim 9
Dependent Claim
27 words
The system of claim 6 wherein the support means comprises a jack, further comprising a crank operatively connected to the jack for extending or lowering the jack.
Claim 10
Dependent Claim
22 words
The system of claim 1 wherein the support means comprises a pair of spaced-apart poles releasably attached to the second rail means.
Claim 11
Dependent Claim
31 words
The system of claim 8 further comprising a cable and a pulley attached to the poles and being adapted to raise or lower a rearward end of the second rail means.
Claim 12
Dependent Claim
34 words
The system of claim 9 wherein the poles are attached to the second rail means by a length of the cable and the platform is free to move vertically with respect to the poles.
